Removing sag from drywall repair
 

I had a leak in bedroom ceiling caused by a tub leak upstairs. Tub has been repaired and now I'm trying to repair ceiling damage. I have cut out a spot about 25''x 8'' in the drywall. When I put in my new drywall I discovered that the drywall had a sag where water had been collecting. My new drywall patch does not sag. I tried to "pull-up" the sag with my screws but it wasn't enough. Do I just fill in the sag with joint compound? Won't this take forever to dry? Help!!!

You can make up a T-shaped 2X4 prop to push the sag up. Or depending how big the sag area is, cut it out and replace with new.
Home Depot sells 2' X 2' patch squares.

You're better off enlarging the hole to get to a level area. If you choose to mud the difference in the pieces, use setting type compound for the fill coat.

cut it out replace the board you will be happier and make the work easier

Sagging Drywall ceiling
 

Thanks to everyone. I just got back from Home Depot for a larger sheet of drywall. I'll try to cut out most of the sag and go from there. Thanks again.
